SPECIFICATION forming part of Letters Patent No. 295,609, dated March 25, .1884.

Application filed September 18,1882. (No model.)

To aZZ whom it may concern: l

Be it known that I, FRANcIs K. ADAMS, a citizen of the United States, residing atNashotah, in the county of Waukesha and State of Wisconsin, have invented certain new and useful Improvements in Car-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such it appertains to make and use the same, ref erence being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in car-coupling.

The object of my invention is to provide a coupling which will retain the link in a true horizontal position preparatory to entering the draw-bar of an approaching car, and which, as it enters the car, will be automatically coupled thereto.

The construction and operation-of my in vention are further explained by reference to the accompanying drawings, in which Figure 1 represents aview of the draw-bar, in part perspective and in part a longitudinal vertical section. Fig. 2 is a longitudinal vertical section. Fig. 3 is a top View, and Fig. 4. is a perspective of the latch.

Like parts are represented by the same reference-letter throughout the several views.

Ais the drawbar. Bis the coupling-link. (l is a latch. The latch O is adapted to be thrown upward by contact with the link as it enters the draw-bar, and to drop of its own gravity as the end of the link passes beneath it, when the point E of the latch passes through the link, and thus retains the link substantially as an ordinary pin.

D is a recess formed in the draw-bar for the reception of the latch. Both the front end of the latch a and front wall of said recess b incline slightly forward and downward, whereby a downward tendency is given to said latch as it is drawn forward against said inclined surface, and is thereby prevented from working upward or bounding out of the link as the train is being drawn. The front end of said latch between a and the point E is curved so as to present a rounded surface to the link as it enters the draw-bar,

atrue horizontal plane parallelto each other,

whereby the link is retained in a nearly horizontal position, and its front end adapted to enter the draw-bar of an approaching car, as mentioned. The recess G extends downward and rearward, so that the latch 0 may be moved rearward by the link before raising, whereby the angular point at cl will escape contact with the front wall of the recess 21 as it rises. The point E of the latch, when drawn forward, rests in the angular recess I, and as said latch is first brought in contact with the link and moved backward it is slightly raised by contact of the point E with the surface of said recess as it moves backward over it when the upward movement of the latch is completed by the action of the link as it is forced beneath it. The front end of the latch is provided with a ring, J, for the reception of a cord or chain, by which it may be raised from the top of a car when desirous to uncouple the device.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isp In a car-coupling, the draw-bar A, provided with horizontal recess H, angular recess 1, vertioal slot D, and recesses G G, .in combination with the latch 0, provided with lugs F F, adapted to operate in said recesses G G, said latch 0 being adapted to be thrown upward by contact with said angular recess I as it is moved rearward by the approaching link preparatory to the link entering beneath it, said horizontal recess H being adapted to hold said link in position to enter an approaching drawbar or coupling, substantially as and for the purpose specified. q

In testimony whereof I affix my signature in presence of two witnesses.
